-2 Check for remaining capacity (battery requiring refilling)
(1) There are two methods of checking the
remaining capacity, measuring the ratio of the
electrolyte and measuring with a battery tester.
(2) When the remaining capacity is low, recharge
immediately.
(3) When the specific gravity ratio of electrolyte is
below 1.220 (20
), recharge it.

(4) Measure using a battery tester and if the range
indicated by the meter is below the yellow
area, recharge it.

DANGER
- If the battery is used or charged with
the electrolyte level indicating below the
<LOWER LEVEL> shown on the side of
battery, the battery may explode.
Immediately refill to the level between
the <LOWER LEVEL> and <UPPER
LEVEL>.
(1) The electrolyte level lowers as it is
decomposed by an electric current. When the
electrolyte is insufficient, and the battery plate
is exposed, the service life of the battery is
shortened eminently.
(2) If the electrolyte level is low, recharge the
electrolyte to the <UPPER LEVEL>.
